not really. but let me tell you a bit of the history.

chuck cranor got the mvme147 up and running (i merely convinced
someone to mail chuck a unit :-). my code is based on chuck's code.
(a lot bunch of things have changed since chuck last touched it!)

dale's stuff is different: quite a bit different actually. some of his
stuff is better, some of our stuff is better. our code is based on the
hp300 tree with device drivers hacked from the sparc and da30 trees.
for the moment i suspect there will be just cross pollination -- i am
definately going to pull in the good things from dale's port -- i do
not know what dale's plans are.

i am under contract with a company to make netbsd run on the
68040-based mvme162 card. i don't have time to switch to dale's
codebase, and i think some of the things i have working now are better
... but, he has scsi working -- our stuff is nfs diskless only at the
moment.  but some of those critical things are a 68040-aware pmap
module, a zs driver that can deal with zs-chip memory arrangement
differences, a driver for the idiotic i82596 chip, etc. i've got the
mvme162 somewhat going, while the same kernel runs fine on the
mvme147. it is faster/easier for me to look at what is better in
dale's port and merge it into my codebase.

dale has an mvme167, which is slightly different from the mvme162
(most significant difference is that it uses a cd1400 serial chip).

by the way, there is an mvme177 board which uses the 68060. apparently
it is quite like the mvme167. there is also a 68060-based mvme172
coming out in about two months, but i haven't been able to find out
what chips are on it. motorola definately overdesigns their boards:
the vmechip on the 162 has 31 interrupt sources (there are many other
sources on the board). i have 6 32-bit 1MHz timers at my disposal..

also, you now know that i'm the mysterious 3rd person interested in
68060 developments...
